Pruning your Dynamite Crape Myrtle is essential to maintain its shape, encourage healthy growth, and promote abundant flowering. Proper pruning helps prevent overgrowth and allows air and sunlight to penetrate the plant, reducing the risk of disease. Here are guidelines for pruning Dynamite Crape Myrtle:

Timing: Pruning is typically done in late winter or early spring, before new growth begins. Avoid heavy pruning during the growing season, as it can remove flower buds and reduce blooming.

Tools: Use sharp and clean pruning shears or loppers for cutting. Make clean, angled cuts to minimize damage to the plant.

Pruning Steps:

Remove Dead or Diseased Wood: Begin by inspecting the crape myrtle for dead or diseased branches. Cut these back to the healthy wood, making clean cuts just above a healthy bud or branch junction. Dispose of the removed material to prevent the spread of disease.

Remove Suckers and Low Growth: Dynamite Crape Myrtle can produce suckers or low, unwanted growth from the base of the plant. Remove these suckers and any branches that are growing too close to the ground.

Thin Out Overcrowded Branches: To improve air circulation and reduce overcrowding, selectively thin out branches that are crossing each other or growing inward. Focus on removing branches from the interior of the canopy.

Raise the Canopy: Raise the canopy by removing lower branches that are obstructing pathways, views, or other plantings. This can be especially important for maintaining a clean and attractive appearance.

Selectively Shorten Branches: If necessary, you can selectively shorten or reduce the length of branches to maintain the desired shape and size. Make cuts just above a healthy bud or lateral branch. Avoid "topping" or severe pruning, as it can lead to weak growth and reduced flowering.

Deadheading (Optional): While not necessary for crape myrtles, deadheading (removing spent flower clusters) can encourage the plant to produce more blooms. If you choose to deadhead, do so after the initial bloom and continue throughout the growing season as needed.

Note: Avoid excessive or "crape murder" pruning, which involves cutting the plant back severely. This practice can harm the plant's long-term health and lead to excessive regrowth that may require further maintenance.

Remember that crape myrtles are resilient, and minor pruning is usually sufficient to maintain their appearance and health. When in doubt, err on the side of caution and prune conservatively. Regular, light pruning is often more beneficial than infrequent heavy pruning for the overall health and aesthetics of your Dynamite Crape Myrtle.
